You are can navigate through your sd card and move, rename, and delete files without removing your sd card. I was also under the impression that you could navigate your USB and a SMB location. But I couldn't figure out how. So I just deleted it and I am back to removing my sd card or plugging my USB drive into my computer.

This is OUTSTANDING. I just recently borrowed my g/f's wii, and I do not have an SD reader here. I was trying to figure out an easy way to copy files to the SD on the wii. This is brilliant, it even has a very, very handy ftp server. Thanks a lot for this, it really helped me out!
